8838

8838 is a natural number that follows 8837 and precedes 8839. It is an even composite number with prime factorization 2 × 3^2 × 491. Because of this factorization, 8838 has 12 positive divisors: 1, 2, 3, 6, 9, 18, 491, 982, 1473, 2946, 4419, and 8838. The sum of its digits is 27, so the number is divisible by 9 and by 3, but not by 27. Its digital root is 9.

In various base representations, 8838 appears as follows: in binary it is 10001010000110, in hexadecimal it is 0x2286, and in octal it is 21206. The number is not prime, and it cannot be expressed as a sum of two squares because it contains the prime factor 491 (which is congruent to 3 modulo 4) to an odd exponent in its factorization. As a result, 8838 serves as an example of an even composite number with a relatively simple factorization and a specific sum-of-squares property.
